Without having tried it, I think the Vogels Sound 1250 can be combined with the Wall 3345. Each TV has 4 screws with which the TV can be mounted on a bracket that supports the standard dimensions of the TV's holes. The lower two of these two screws need to have the Vogels soundbar bracket screwed into them, presumably under the bracket arms. It may be necessary to compensate for the difference in level of the upper two screws with washers or something similar, because the two soundbar brackets are located under the lower part of the arm so that the TV is nicely vertical in the normal position.
